A 30-year-old female came to the emergency department complaining of recurrent episodes of fearfulness, palpitations, faintness, hyperventilation, dryness of the mouth with peri-oral tingling and cramping of the hands. These symptoms generally last 5-10 mins and have worsened since their onset 3 months ago. An ECG shows sinus tachycardia. What is the single most appropriate immediate intervention?
Your Answer: High flow oxygen
Correct Answer: Rebreathe into a paper bag
Explanation:History is suggestive of a panic attack which causes her to hyperventilate. This has washed out the CO2 leading to a respiratory alkalosis. This causes increased calcium ion binding to albumin and a reduction of free calcium in the blood which causes peri-oral tingling and cramping of the hands. These symptoms can be improved by rebreathing into a paper bag which will reverse the above mechanism.

A 12-year-old boy hit his head on a pole on the school playground. His friends noted that he lost consciousness for a few seconds. The school nurse sent him to the Emergency Department as he had a small nasal bleed that stopped spontaneously. In the intervening two hours, he has noticed a watery discharge from his nose. On examination, there is considerable bruising on his nose and forehead, he was complaining of a headache. Which is the most appropriate diagnosis?
Your Answer:
Correct Answer: Basilar skull fracture
Explanation:Orbital bone fracture: The child has sustained a head injury and subsequently describes a CSF rhinorrhoea (indicating a cerebro-spinal fluid leak). CSF rhinorrhoea can occur in skull or nasal bone fractures. Given the symptoms of loss of consciousness and headache, this child is more at risk of having suffered a skull fracture requiring emergency CT head investigation and specialist neurosurgical management. An ethmoid bone fracture may also present this way. A skull x ray would help to determine an air fluid level and indeed allow some visualisation of the nasal bones, though in children the nasal bones do not visualise well due to lack of fusion. Either way this child would need assessment in the nearest Emergency Department and the school would be expected to follow a ‘head injury’ protocol.

A 75-year-old man was admitted with urinary dribbling and incontinence. Upon examination, there is a palpable mass up to the umbilicus. His clothes smell of ammonia and he is known to be a chronic alcoholic. What is the next most appropriate step?
Your Answer:
Correct Answer: Urethral catheter
Explanation:It is obvious in this case that chronic alcohol use has contributed to the patient’s urinary incontinence which requires a urethral catheter. Suprapubic catheters are usually preferred in cases of acute urinary retention while condom catheters are indicated in less severe cases of urinary incontinence. We would administer antibiotics if we suspected a urinary infection causing the urinary incontinence, but in this case the cause is obvious.
